Ocular effects of apraclonidine in Horner syndrome.
OBJECTIVE To determine the location of action of apraclonidine, an alpha-adrenergic receptor agonist that reduces aqueous production and lowers intraocular pressure (IOP). METHODS The study cohort consisted of 6 patients with Horner syndrome (decreased or absent sympathetic innervation of 1 eye). We instilled 1% apraclonidine into the affected eye, and the changes in IOP and pupil diameter (P...
